NWS Pendleton, OR wrote its last area forecast discussion before the first event at Dec 2, 8:20 AM PST, 1 hour 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PENDLETON OR 820 AM PST FRI DEC 2 2005 .SHORT TERM...UPPER TROUGH AXIS IS NOW MOVING ACROSS THE FORECAST AREA WITH A COLD AND UNSTABLE AIR MASS. TEMPERATURES AT THE SURFACE HAVE RISEN OVERNIGHT DUE TO MIXING WITH INCREASING WINDS. HOWEVER TEMPERATURES ALOFT AT 500MB ARE VERY COLD...ABOUT -35 TO -40 C. THIS COMBINED WITH MOISTURE IN THE LOWER LEVELS AND STEEP LAPSE RATES WILL RESULT IN SCATTERED CONVECTIVE SNOW SHOWERS TODAY (POSSIBLY RAIN SHOWERS IN THE BLUE MOUNTAIN FOOTHILLS AND COLUMBIA BASIN THIS AFTERNOON WHERE THE AIR IS WARMER AND CURRENTLY IN THE LOWER TO MID 30S). UPPER TROUGH PASSES TO THE EAST TONIGHT AND IS REPLACED BY A NORTHWEST FLOW ON SATURDAY. THERE WILL STILL BE SUBSTANTIAL MOISTURE IN THE LOWER LEVELS WITH VERY COLD AIR ALOFT...SO A MENTION OF CONTINUED CHANCE OF SNOW SHOWERS...ESPECIALLY IN THE NORTHERN BLUE MOUNTAINS WHERE UP SLOPE WILL BE GREATEST...IS WELL WARRANTED. LATEST GFS AND ETA MODEL RUNS HAVE BACKED OFF ON THE ARCTIC AIR FOR NEXT WEEK...BUT IT STILL APPEARS THAT A NORTHERLY FLOW WILL DEVELOP AND BRING SIGNIFICANT COLD AIR INTO THE CWA BY THE MIDDLE OF NEXT WEEK. 88 && .PREV DISCUSSION... (ISSUED 245 AM PST FRI DEC 2 2005) SHORT TERM...TODAY THROUGH SUNDAY. THE FORECAST AREA WILL BE UNDER THE INFLUENCE OF A COLD UPPER TROUGH THROUGH EARLY SATURDAY. THE TROUGH WILL SHIFT EASTWARD SATURDAY AS HIGH PRESSURE STRENGTHENS OFF THE COAST. THE AREA WILL THEN BE INFLUENCED BY A NW FLOW ALOFT THE REMAINDER OF THE WEEKEND. SCATTERED SHOWERS ARE EXPECTED THE NEXT 24 HOURS AS SEVERAL WAVES EMBEDDED IN A WESTERLY FLOW MOVE ACROSS THE REGION. NUMEROUS SHOWERS ARE OCCURRING WEST OF THE CASCADES WITH SNOW SHOWERS SPREADING ACROSS THE EAST SLOPES. SHOWERS WILL MAINLY BE CONFINED OVER THE MOUNTAINS TODAY AND TONIGHT...AS WESTERLY WINDS WILL PROVIDE SOME SHADOWING OVER THE COLUMBIA BASIN. ONE CHALLENGE WILL BE SNOW ACCUMULATIONS WITH SNOW SHOWERS TODAY. THE AIR MASS IS UNSTABLE WITH COLD AIR ALOFT...AND THERE COULD BE A FEW SHOWERS THAT WILL DUMP HEAVY SNOW IN A SHORT PERIOD OF TIME. WILL HANDLE THESE SITUATIONS WITH NOWCASTS. NO MAJOR WEATHER CONCERNS SATURDAY-SUNDAY. SCATTERED SHOWERS WILL MAINLY BE CONFINED TO THE MOUNTAINS SATURDAY. SHOWERS WILL TAPER OFF SATURDAY NIGHT AS A DRIER NW FLOW ALOFT SPREADS ACROSS THE REGION. ON SUNDAY...ONLY ISOLATED SNOW SHOWERS ARE EXPECTED. SMITH LONG TERM...RIDGE OF HIGH PRESSURE WILL BE ALONG THE COAST PROVIDING A COOL NORTHWEST FLOW. MOISTURE WILL BE LIMITED SO JUST SLIGHT CHANCE OF PRECIPITATION FROM TIME TO TIME AS SYSTEMS CLIP THE FORECAST AREA IN THIS NORTHWEST FLOW. AVIATION...VFR AND MVFR CONDITIONS EXPECTED WITH CEILINGS AND VISIBILITY REDUCED BY LIGHT SNOW SHOWERS THROUGHOUT THE DAY AS AN UNSTABLE AIR MASS MOVES OVER THE REGION. && .PRELIMINARY POINT TEMPS/POPS...
